Major accomplishments

WTSA-24: Discussions on the preparations for WTSA-24 completed under the SG16 ad hoc group of the plenary on WTSA-24 preparations (AHG-WTSA24). The text of the current SG16 mandate was updated [TD243/Plen] as well as the text of the existing Questions [TD244/Plen, TD245/Plen, TD246/Plen, TD247-R1/Plen], in particular to include metaverse study items and tasks that were pending guidance from TSAG. A proposal to create a new Question on metaverse [TD248/Plen] was not agreed (see metaverse discussions bullet, below). The group was briefed on the consensus in TSAG that ITU-T SG16 would be consolidated with ITU-T SG9 (on broadband cable and TV) as a single group in the next study period (2025-2028); a joint team of SG9 and SG16 management was mandated to develop the terms of reference for the consolidated group.
Metaverse: With the first FG-MV deliverables being approved by TSAG and some delivered to SG16, the mandate of the SG and Questions were updated to include metaverse study areas and tasks. In addition, one of the deliverables was approved as technical paper and one new work item was established based on the deliverables. SG16 also provided feedback to TSAG on interest concerning other deliverables (present and future), as found in [SG16-LS153]. The text of a proposed (but not agreed) Question on metaverse cross-platform interoperability in multimedia aspects was also shared with TSAG, for advice. SG16 also created an ad hoc group of the plenary on metaverse (AHG-MV) to help progress the metaverse standardization work in the study group between this and the next meeting [TD216-R2/Plen] (mailing list message / subscription / archive; IFA).
Focus groups: The final report of the Focus Group on AI for health (FG-AI4H) was reviewed, with the list of 36 approved deliverables. It concluded activities on 30 September 2023, after its last meeting in Geneva, 3-5 July 2023. Questions 5/16 and 28/16 will review the deliverables for possible transposition as ITU-T SG16 deliverables. The results of the FG-AI4H will be used as foundation for the ITU, WHO and WIPO Global Initiative on AI for Health being put into place [SG16-TD202/Plen, SG16-TD203/Plen]. No other FGs remain under SG16, after closure in September 2022 of FG-VM (on vehicular multimedia) and FG-AI4AD (on AI for autonomous and assisted driving).

Question 6/16 summary

The primary goals for Question 6/16 at this meeting of SG16 were to review the progress of Q6/16, JVET, and JPEG work, prepare texts for Consent, and plan for additional work items. On topics related to the coding of video, a substantial portion of the video coding work of Question 6/16 is being conducted jointly with ISO/IEC JTC1/SC29 in JVET. A collocated meeting of JVET was held under the auspices of this meeting of SG16, and the MPEG working groups and advisory groups of SC29 also met in a collocated fashion, providing the opportunity for coordination and joint meeting discussions with these groups. JVET is tasked with maintenance and enhancement of H.26x video coding Recommendations including VVC, HEVC, and AVC, and also the associated Rec. H.274 VSEI and Rec. H.273 CICP standards and some other related matters. JVET has also been conducting exploration studies of future video coding technologies for potential development of new video coding standards with advanced capabilities beyond the current state of the art. Joint meeting sessions of Q6/16 with JVET (aka SC29/WG5), SC29/AG5, SC29/WG2, and SC29/WG4 were held during the current meeting of SG16, for discussion of areas of joint interest. At this meeting, four revised twin text Recommendations on video coding-related subjects were Consented under AAP (H.264 V15, H.265 V10, H.266.2 V2, and H.273 V4) and six planned revisions of video coding-related Recommendations were added to the work programme. On topics related to the coding of images, a substantial portion of the image coding work of Question 6/16 is conducted jointly with ISO/IEC JTC1/SC29/WG1 (JPEG). At this meeting, one common text with ISO/IEC on image coding was Consented (ITU-T T.800 V4) and six additional new work items on image coding topics were added to the work programme; four of these new WIs are part of the joint JPEG work on "JPEG AI" image coding. Q6/16 also established a new work item for the development of a new Recommendation H.BWC for biomedical and general waveform coding. A Call for Proposals was approved soliciting technical contribution proposals for the H.BWC project. Two Rapporteur meetings are planned in the interregnum period, collocated with JVET meetings. The Question prepared seven outgoing Liaison Statements, four of which were produced within JVET and forwarded by Q6/16 for approval by SG16.

Question 8/16 summary

Question 8/16 met for eight sessions to discuss 17 contributions and several input liaison statements with 20 experts in attendance, physically and remote. As a result, draft Recommendation H.430.8 (ex H.IIS-FA) consented and four new WIs were established. It also progressed two ongoing WIs, H.ILE-AMR and H.ILE-QR, based on received contributions. No existing items were discontinued. Four outgoing LSs were prepared, and the ToR of Q8/16 was agreed. Q8/16 experts plan one rapporteur group meeting in August 2024.

Question 11/16 summary

Q11/16 did not have sessions during this SG16 meeting, but the Rapporteur informed the meeting that the ASN.1 updates in the recently revised H.225.0 and H.245 changes are confirmed to be correct.

Question 26/16 summary

Question 26/16 reviewed proposals concerning metaverse accessibility, with eight contributions that were mostly based on deliverables from the ITU-T Focus Group on metaverse (ITU FG-MV) and submitted one Technical Paper for approval at this meeting and another one as a new work item for a Technical Paper. The Question also submitted for agreement ITU-T FSTP-CONF-F.780.2 with the conformance testing specification for ITU-T F.780.2 (accessibility of telehealth services). New work item F.ACC-AMCS was created on ICT accessibility in rural areas and developing countries as well as temporary disruptions, out-of-home situations, and disruption by disasters. Work also started on a revision of ITU-T F.910 that defines multimedia telecommunication relay services. A liaison statement was prepared with Q28/16 to ILO concerning accessibility at the workplace and safety. Q26/16 plans one interim rapporteur group meeting.

Question 27/16 summary

Question 27/16 met for seventeen sessions to review 12 contributions. One text was submitted for AAP consent, ITU-T F.749.18 (ex F.CUAV-ES). TAP consultation results about F.749.7 and F.749.17 were discussed and experts agreed not to pursue approval as Recommendations, but rather to develop two new Technical Papers based on the existing texts. Q27/16 progressed on work items including F.PB-ADS-DV, H.MVIS, H.VG-VRU, F.DVMSF-Edge and F.VSAI-ARCH and agreed to start five new work items on F.CAV-MIFS, F.CAV-CDP, F.VM-AVP, F.VM-SPEECH and F.VGP-PARK at this meeting. Two outgoing liaison statements were produced. Q27/16 plans two meetings in the interim period.

Question 28/16 summary

Question 28/16 made significant progress on digital health studies. A joint ITU/WHO Workshop on E-sports and video gaming was hosted, the safe listening for video-gaming and esports (H.SL-ES) draft has been progressed, as well as the drafts for person-generated health record (F.HR-AP) and occupational health service platform (F.OHSP-req). Two Technical Papers were submitted for agreement, revised ITU-T HSTP-CONF-H870 for testing compliance of personal audio systems with ITU-T H.870 (V2) and new FSTP.MED-THS with an outline and elements of basic telehealth services. The group plans four meetings in the interregnum period. The Question produced one outgoing LS together with Q26/16.
